【発明の詳細な説明】
〔産業上の利用分野]
この発明は、自動車の生産ラインにおいて、複数種のボ
デーを効率良(搬送するボデー搬送方法に関するもので
ある。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a body transport method for efficiently (transporting) a plurality of types of bodies in an automobile production line.
[従来の技術]
自動車の生産ラインは大別して、ボデー工程、塗装工程
、組立工程から成っている。そして各工程では、ボデー
を作業姿勢に合わせて適宜の搬送手段で各作業ポジショ
ンへ連続送り、或いは、間欠送りを行って生産している
。[Prior Art] An automobile production line can be broadly divided into a body process, a painting process, and an assembly process. In each process, the body is continuously or intermittently fed to each working position using an appropriate conveyance means in accordance with the working posture during production.
また上記生産ラインは、−ラインで−II類の車両を生
産するのではなく、−ラインで車種や仕様の異なる複数
種の車両を生産する混流生産が行われている。従って上
記ラインでは、車種や仕様のことなるボデーを一定間隔
で順番に流している。In addition, the above-mentioned production line does not produce class -II vehicles on the - line, but performs mixed production in which multiple types of vehicles with different vehicle types and specifications are produced on the - line. Therefore, on the above line, bodies of different car models and specifications are passed in sequence at regular intervals.
従来、ボデーの搬送は、ボデー工程や組立工程では、例
えば、スラットコンベアのスラントに固定のアタッチメ
ントを取付け、該アタッチメントにボデーを支持させて
搬送したり、或いは、ボデーを載せた台車をチェーンコ
ンベアで駆動して搬送したりしている。Conventionally, bodies have been conveyed in the body process or assembly process by, for example, attaching a fixed attachment to the slant of a slat conveyor and having the body supported by the attachment and conveying the body, or by transporting a cart carrying the body on a chain conveyor. It is driven and transported.
[発明が解決しようとする課題〕
混流生産では、車種や仕様の違いによって仕様する部品
や作業内容が異なってくる。そのため、ボデーを搬送す
る際、作業量の平準化、販売台数に基づく生産比率等を
考慮した順序でボデーを流すようにしている。しかし前
記順序は常に一定とならず、たえず変わっている。そこ
でボデーの送り順序を入れ替えてもその都度搬送手段を
構成し直さなくてもよいように、ボデーを一定のピッチ
で送っている。[Problems to be solved by the invention] In mixed production, the parts and work content to be specified differ depending on the vehicle model and specifications. Therefore, when transporting the bodies, the bodies are transported in an order that takes into account the leveling of the workload, the production ratio based on the number of units sold, etc. However, said order is not always constant and is constantly changing. Therefore, the bodies are fed at a constant pitch so that even if the feeding order of the bodies is changed, the conveying means does not have to be reconfigured each time.
しかし、上記方法では、大きさの大きく異なる複数種の
ボデーを流す場合では、最も大きいボデーに合わせたピ
ッチで全てのボデーを流さねばならず、ラインが非常に
長くなると共に、ボデーの大きさの違いによって各ボデ
ー間の間隔が変わるため、作業ボジシッンへ送られてく
るタイミングが異なり、作業がやり難くなっていた。However, with the above method, when multiple types of bodies with widely different sizes are flown, all the bodies must be flown at a pitch that matches the largest body, resulting in a very long line and an increase in the size of the bodies. Because the spacing between each body changes depending on the difference, the timing at which the parts are sent to the work body varies, making the work difficult.
この発明は、ボデーの種類に合わせてピッチを変えて送
れるようにした搬送方法を提供しようとするものである
。The present invention aims to provide a conveying method that can change the pitch depending on the type of body.
(課題を解決するための手段)
この発明は、ボデーを載せたパレットを一定速度で送る

空になったパレットを返送コンベアへ戻す戻し手段とを
有し、前記投入手段で待機しているパレットに載せられ
たボデーの種類に合わせて、送りコンベアへのパレット
の投入タイミングを変えるようにしたものである。(Means for Solving the Problems) This invention provides a feed conveyor that sends pallets loaded with bodies at a constant speed, a return pallet that returns empty pallets, and a return conveyor that is installed behind the starting end of the feed conveyor. A loading means is installed in front of the terminal end of the feeding conveyor, and a loading means is installed in front of the terminal end of the feeding conveyor.
and a return means for returning the empty pallet to the return conveyor, and the timing of feeding the pallet to the sending conveyor is changed according to the type of body placed on the pallet waiting by the feeding means. It is something.
上記方法であれば、ボデーを載せたパレットを送りコン

作業ポジションへ最適な間隔、並びに、タイミングで送
れる。With the above method, the pallet carrying the bodies is fed into the feeding conveyor and conveyed, so the feeding order and spacing of the bodies can be easily changed. Additionally, since the timing at which pallets are loaded onto the feed conveyor is adjusted according to the type of bodies placed on them, even in mixed production, each body can be sent to the work position at optimal intervals and timing.
